Materials associated with the DNA fraction of Bacillus subtilis W168

Creator:: Laudermilk, Patricia Joan
Abstract:: The purpose of this research was to determine if a basic protein was associated with the DNA of Bacillus subtilis W168, and to determine if there was a difference in the amount and type of protein associated with the DNA at different times during the growth cycle of the organism....

Photosynthetic Energy Allocation Strategies of Thalassiosira pseudonana During Light Limited Growth

Creator:: Fisher, Nerissa L.
Abstract:: Photosynthetic energy allocation strategies were investigated in the marine diatom, Thalassiosira pseudonana, grown under a wide range of light limitation. Steady-state, continuous cultures were established at three light-limited growth rates. Simultaneous measurements of photosynthetic activity were made that targeted different points in photosynthetic energy flow from gross to net photosynthesis....

A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

Creator:: Ley, Ronald Douglas
Abstract:: Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

Growth and development of tetracycline resistant Chlamydia suis

Creator:: Lenart, Jennifer
Abstract:: Tetracycline is a front line antibiotic for the treatment of chlamydial infections in both humans and animals, and the emergence of tetracycline resistant (tet[superscript R]) Chlamydia is of significant clinical importance. Recently, several tet[superscript R] chlamydial strains have been isolated from swine (Sus scrofa) raised in production facilities in Nebraska....

Development of an enzyme-linked immunosorbent assay to detect antibodies against Bacillus thuringiensis subspecies israelensis in Mallard ducks (Anas platyrhynchos)

Creator:: Rutherford, Gregory J.
Abstract:: To develop an assay to detect antibodies to Bacillus thuringiensis subsp. israelensis in mallard ducks, a growth curve was first established for the bacterium. The growth curve indicated that the crystal delta endotoxin would be best harvested from the rest of the cell material after 12 hours of growth. The...

Bdellovibrio metabolism of host macromolecules

Creator:: Engelking, Henry Mark
Abstract:: The genus Bdellovibrio is characterized by the unique ability to parasitize and enter gram-negative host bacteria. This interaction leads to the consumption and death of the host cell as the Bdellovibrio grows and divides into progeny. Little is known about the metabolism of host cell components by Bdellovibrio. The possibility...

Transcriptome Responses of the Nitrifying Bacteria Nitrosomonas europaea and Nitrobacter hamburgensis to Low Oxygen

Creator:: Dobie, Michael
Abstract:: Nitrification is the process within the global Nitrogen Cycle where ammonia (NH3) is oxidized to nitrate (NO₃⁻) and can be carried out by two distinct groups of bacteria. The ammonia-oxidizing bacteria (AOB) first oxidize NH₃ to nitrite (NO₂⁻), and second, the nitrite-oxidizing bacteria (NOB) oxidize NO₂⁻ to NO₃⁻. In aerobic...

A comparative study of fish coloration and toxicant responses in a chromatophore cell-based biosensor

Creator:: Roach, Holly B.
Abstract:: Detection of both biological and chemical environmental toxicants is essential in the assessment of risk to human health. Cell-based biosensors are capable of activity- based detection of toxicity. Chromatophore cells, responsible for the pigmentation of poikilothermic animal, have shown immense potential as cell-based biosensors in the detection of a broad...

Susceptibility of two salmonid fish cell lines to two viruses from fish and two from homothermic animals

Creator:: Nims, Linda Jean
Abstract:: This thesis describes the viral susceptibility of two cell cultures established from embryonic tissue of salmonid fish, chinook salmon line CHSE-114 and steelhead trout line STE-137. The viruses used were Oregon sockeye salmon virus (OSV), Sacramento River chinook disease virus (SRCD), Western equine encephalitis virus (WEE) and Newcastle disease virus...

Analysis of segregants of F'gal heterogenotes in Escherichia coli

Creator:: Kurahara, Carole Mahaney
Abstract:: The purpose of this study was to isolate and characterize any segregants of the heterogenotes formed from sexduction by an F' donor. Following the mating of F' W4520, carrying an F' gal₁⁺ gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a number of recombinant clones were picked and examined for...
